The DO-214AB (SMC) package footprint mates with standard SMCJ land patterns — no special pad geometry needed for the 1500W rating as long as the copper area follows the datasheet's recommended solder land. Single unidirectional channel means it is wired with polarity — cathode to the protected rail, anode to ground — and is suited for DC bus or signal line protection where the voltage never reverses. The Zener breakdown mechanism gives a tight clamping window: 171V minimum breakdown versus 246V maximum clamp at the 6.1A peak pulse current. ## Temperature range and thermal integration The 150°C TJ ceiling means derating the peak pulse power above 25°C per the datasheet curve — at 125°C ambient the effective pulse power drops to roughly 60% of the 1500W rating, which matters for high-temperature enclosures or engine-bay deployment. Surface mount on the DO-214AB package requires the PCB copper pad to sink the transient heat pulse. The 1500W rating assumes a standard FR-4 board with adequate copper area under the cathode tab; a 4-layer board with thermal vias into an inner ground plane improves the thermal impedance margin for repetitive pulse trains. No pin-compatible successor or second-source cross-reference is registered for this specific breakdown voltage variant within the 1.5SMC family. For BOM continuity, the 1.5SMC series covers a full voltage ladder from 5V to 220V, so a parametric alternative at a different standoff voltage exists within the same package family if the protected rail voltage changes.","metaTitle":"Vishay 1.5SMC180A-E3/9AT 1500W TVS Diode, 154V Standoff","metaDescription":"Vishay 1.5SMC180A-E3/9AT TransZorb TVS diode, 1500W peak pulse power, 154V reverse standoff, DO-214AB SMC.
